Jumu'ah ( ) (also known as
jum'ah, Friday prayer,
etc.) is a congregational prayer (salat) that Muslims hold
every Friday, just after noon in lieu of
dhuhr. It is mentioned in the
Qur'an as: The jumu'ah prayer is half
the dhuhr prayer, for convenience, preceded by a
khutba (a sermon as a technical
replacement of the two reduced raka'ahs of the ordinary dhuhr
prayer), and followed by a communal prayer, led by the imam. In most cases the khaṭīb
also serves as the imam. Attendance is strictly incumbent upon all
free adult males who are legal residents of the locality, females
are also permitted to go to the Mosque to perform the Friday
prayers, and have a section that is separated from men in which
they pray with fellow Muslim women, though it is only obligatory on
all free Muslim males.

The muezzin makes the call to prayer, called
the adhan, usually 15-20 minutes prior to the
start of Jum'ah. When the khaṭīb takes his place on the minbar, a second adhan is made.
The khaṭīb is supposed to deliver two speeches, stopping and
sitting briefly between them. In practice, the first speech is
longer and contains most of the content. The second speech is very
brief and concludes with a du'a, after which
the muezzin calls the iqama. This signals the start of the main two rak'at
prayer of Jumu'ah.

The prayers mainly have high attendance of worshipers, as compared
to the ritual prayers. In Turkey for example,
the ritual prayers are performed regularly by 44%, whereas going to
Friday prayers was more regularly attended by 56% (25% responded
that they sometimes attended and 19% that they never
did).

Abu Hurayrah reported that Muhammad said: "When it is Friday, the
angels stand at every door of the mosque and record the people in
order of arrival, and when the Imam sits on the pulpit for
delivering the sermon, qutba, they fold up their sheets and listen
to the mention of Allah, the speech."

A person who goes to Friday prayer is said to have his sins between
that Friday and last forgiven.
